Diarrhea is common in children and often caused by short-term illnesses such as viral infections or dietary changes. In most cases, symptoms resolve on their own within a few days. However, when diarrhea becomes persistent or recurrent, it may signal an underlying gastrointestinal condition that requires further evaluation by a pediatric gastroenterologist.
Understanding when diarrhea is no longer “just a stomach bug” can help parents seek timely care and prevent complications.
What Is Considered Persistent Diarrhea?
Persistent diarrhea is generally defined as loose or watery stools lasting more than two weeks, or diarrhea that repeatedly returns over time. Chronic diarrhea may interfere with a child’s growth, hydration, nutrition, and daily activities.
While occasional loose stools can be normal, ongoing diarrhea should not be ignored.
Potential Causes of Persistent Diarrhea in Children
Several medical conditions can contribute to ongoing diarrhea, including:
-
Food intolerances or allergies
-
Lactose intolerance or carbohydrate malabsorption
-
Celiac disease
-
Inflammatory bowel disease (Crohn’s disease or ulcerative colitis)
-
Infections that do not fully resolve
-
Irritable bowel syndrome (IBS)
-
Small intestinal bacterial overgrowth (SIBO)
-
Pancreatic or bile-related disorders
Identifying the underlying cause is essential for effective treatment.
Warning Signs That Require Further Evaluation
Certain symptoms alongside diarrhea suggest the need for prompt medical assessment, including:
-
Blood or mucus in the stool
-
Unintentional weight loss
-
Poor growth or delayed development
-
Persistent abdominal pain
-
Fatigue or weakness
-
Fever
-
Signs of dehydration
These findings may indicate an inflammatory, infectious, or malabsorptive condition.
